Quietly)) - Toyota Land Cruiser, 4.7 l., 2004

So I gathered my strength and carried out the procedure for soundproofing.
Was done:
1. noise isolation of the entire perimeter of the car (this is a 4-door trunk with a lyada)
2. Floor from the front partition to the rear lyada
3. And of course the ceiling.

During the process, I was struck by the absence of any
insulation in the doors ... except for a bag, nothing was.
Well, as for the final result, it became quiet in the car)
